Emmanuelle IV (1984)

The guy has a thick dark beard and short hair, looks mid-30s, shirtless and muscular in dim light. He’s inside a barn, lying back while a slim brunette with long light brown hair rides him cowgirl, hay scattered around. Later she’s on all fours, bouncing hard in doggy as he grips her hips — you see her back arch and the sweat on her skin. Cut to her swinging outdoors, solo, legs bare, swinging high in a garden with natural light, no top on, swinging back and forth slowly. Back inside, she goes down on him, deep throat, mouth wide, his hand on her head. The camera stays wide during sex, close-up only on his face at the start, dim lighting throughout, candles flickering in one shot. The mix of outdoor calm and rough barn sex stands out — real contrast in mood and pacing.
